Sapphire Plug-ins for Autodesk: BrushChalkMaskComp

BrushChalkMaskComp

In the S_BrushMaskComp Plugin.

Simulates the look of a chalk drawing by layering brush strokes of different sizes and directions. This effect can be used with one of the following brushes: felt tip, splat, water color, stipple, pencil, pastel, sponge, splodge, round, or cubes. In addition, there are controls for adjusting shape, size, orientation, density, lighting, and shading.

Inputs:

Source:
The clip to be processed.

Back:
Optional.
The clip to use as background.

Mask:
Optional.
The source brush colors are scaled by this input. A
monochrome Mask can be used to choose a subset of Source areas that
will generate brushes. A color Mask can be used to selectively adjust
the brush colors in different regions. The Mask is applied to the
source before the brushes are generated so it will not clip the
resulting brushes.

Matte:
Optional.
Specifies the opacities of the Front clip. These
values are scaled by the Source Opacity parameter before being used.

Parameters:

Load Preset:
Push-button
.
Brings up the Preset Browser to browse all available presets for this effect.

Save Preset:
Push-button
.
Brings up the Preset Save dialog to save a preset for this effect.

Max Size:
Default:
1.5,
Range:
0 to 10,
Shared
.
Sets the maximum brush size. No brushes will be larger than this size.

Comp Premult:
Check-box, Default:
off,
Shared
.
Enable this for a better composite if the Front
pixel values have been pre-multiplied by the Matte pixel values.
This is also known as an 'additive' composite.

Contour Alignment:
Default:
0.5,
Range:
0 to 1,
Shared
.
Interpolates between the brush stroke direction being fully aligned to the angle param (0) and the contours of the original source (1). Vary angle offsets the stroke in both directions from this interpolated direction.

Vary Position:
Default:
1,
Range:
0 to 10,
Shared
.
Shifts the brush positions randomly in all directions. A value of zero places all the brushes on a regular grid.

Seed:
Default:
0.123,
Range:
0 or greater,
Shared
.
Used to initialize the random number generator. The actual
seed value is not significant, but different seeds give different
results and the same value should give a repeatable result.

Invert Mask:
Check-box, Default:
off,
Shared
.
If enabled, inverts the mask input so the effect is applied
to areas where the Mask is black instead of white.

Params3:

Blur Mocha:
Default:
0,
Range:
0 or greater,
Shared
.
Blurs the Mocha Mask by this amount before using.
This can be used to soften the edges or quantization artifacts of
the mask, and smooth out the time displacements.
